Problems solved by technology

[0004] However, in Patent Document 1, since the opening at the front end of the handle operation pipe is fitted downward during storage, there is a problem that the dust remaining in the handle operation pipe and the hose falls and dirty the room.
[0005] On the other hand, according to Patent Document 2, although it is also mentioned in Patent Document 1, the hanging part of the handle operation tube is a structure that is fixed only on the predetermined front closing part, so when the user performs compact storage, it is inserted. troublesome, poor operability
[0006] In addition, since it is firmly fitted at a predetermined position, if force is applied in an unreasonable direction when detaching, or if force is applied to the fitting part when it comes into contact with the hose, the fitting part may be damaged.

Abstract

The invention relates to an efficient electric dust collector when the electric dust collector is compact more simply. In the invention, an approximately L-shaped hang part is formed at the front end part of a handle operating tube so that the handle operating tube hangs on the end opening part of a prolonged tube and the problem of dust spattering is solved, and a structure causing the structure of the hang part not to be damaged easily so that the dust collector with fine use convenience can be provided.

Description

technical field [0001] The present invention relates to an electric vacuum cleaner that is effective when the electric vacuum cleaner is more simply and compactly housed. Background technique [0002] Existing electric vacuum cleaners have proposed the following technical solutions. For example, as disclosed in Patent Document 1 (Japanese Patent Application Laid-Open No. 8-191781), a concave portion is formed on the side of the telescopic extension tube and a convex portion is formed on the side of the handle operation tube. Therefore, when retracting, the bending joint is removed from the telescopic extension tube, the above-mentioned concave-convex part is fitted, and the opening of the handle operation tube is turned downward to perform retraction. [0003] In addition, the following technical proposal has also been proposed. As disclosed in Patent Document 2 (Japanese Unexamined Patent Application Publication No. 2007-202831), a hanging portion is provided on the hose co...
